ANK Seals

What ANK Seals does

ANK Seals is an Indian manufacturer founded in 1995 and headquartered in Nagpur, Maharashtra, specializing in hydraulic and pneumatic seals used in heavy industrial applications. The company serves customers across steel, cement, mining, petrochemicals, infrastructure, power, and pharmaceuticals, with named enterprise accounts including Tata Steel, Jindal Steel, Vedanta, Reliance, Aditya Birla Group, JSW, Ambuja Cement, ACC Cement, Gmmco-Cat, and Bombay Dyeing. According to company-reported figures, ANK has delivered more than 500,000 seals over its 25+ year operating history and operates with a workforce in the 11–50 employee range. Mukund Kamath is the listed contact principal for the business.

The company's product portfolio extends well beyond finished seals and includes proprietary capital equipment and consumables: the Ank Swift CNC systems (capable of producing seals up to 700mm OD), ANK Made CNC tools, ANK PUFYL foam-filled tyre technology, and in-house ultrasonic testing capability. ANK also produces its own raw materials (semi-finished tubes) and supplies these to other seal manufacturers, indicating a merchant-material business alongside its own finished-goods line. Sophisticated simulation software is used in seal design to support dimensional and performance accuracy.

The business model is built on direct B2B sales of precision-engineered seals and related capital equipment into Indian heavy-industry customers, supplemented by merchant supply of raw materials and CNC tooling. Revenue is generated through product sales across multiple industrial verticals; the company is privately held, has not raised external capital, and operates entirely within India with no disclosed export activity. The vertical integration — spanning raw-material compounding, in-house CNC machinery and tooling, proprietary testing, and finished seal manufacturing — is the structural backbone of the operating model.

Core offering

ANK Seals is a vertically integrated sealing solutions manufacturer that designs and produces hydraulic and pneumatic seals (rod seals, piston seals, rotary shaft seals, O-rings, guide and back-up rings, and wipers) using proprietary CNC machining. The company also manufactures the supporting value chain—polyurethane and rubber raw material tubes, Ank Swift CNC seal-making machines (500 and 750 series), precision CNC tools, and ANK PUFYL polyurethane foam for puncture-proof pneumatic tyres—primarily for enterprise industrial customers.

Product overview

ANK Seals is an end-to-end sealing solutions provider offering a comprehensive portfolio of industrial sealing products and manufacturing equipment. The core offering consists of hydraulic and pneumatic seals including rod seals, piston seals, rotary shaft seals, O-rings, guide rings, back-up rings, and wipers—all manufactured in-house using proprietary raw materials (polyurethane tubes from European prepolymers and rubber tubes from Japan/Korea). Supporting the seal product line are two proprietary CNC machine models (Ank Swift 500 and Ank Swift 750) for seal manufacturing, in-house developed CNC tools, and ANK PUFYL—a two-component polyurethane foam for converting pneumatic tyres into flat-proof, puncture-proof alternatives. The company also provides raw materials to other seal manufacturers, positioning itself as both a product and equipment solutions provider.
